Abstract:
During 1981 and 1984 flights of the Space Shuttle, the Measurement of Air Pollution from Satellites (MAPS) instrument measured carbon monoxide (CO) using gas correlation filter radiometry. Correlative measurements from the ground and aircraft of CO in the middle troposphere were inconsistent. In the 1994 MAPS flights, a correlative measurement program was designed and ... carried out to maximize the intercomparison between the satellite and aircraft, ground and ship measurements. The correlative data, which are presented in this database, provide an internally consistent, ground-based picture of CO in the lower atmosphere during Spring and Fall 1994. The data show the regional importance of two CO sources: fossil-fuel burning in urbanized areas and biomass burning in various regions of the Southern Hemisphere (Novelli et al. 1998).

Eleven PIs and Co-PIs from organizations around the world conducted ground-based, aircraft, and shipboard measurememnts of CO from stations aross the globe. Data sets, calibration files, and programs are included in DB-1020. The data is available online from CDIAC via ftp or the WWW.

Quality
The Carbon Dioxide Information Analysis Center (CDIAC) quality assures (QAs) data before distribution. Data received by CDIAC are rarely in a condition that would permit immediate distribution, regardless of the source. To guarantee data of the highest possible quality, CDIAC conducts QA reviews that involve examining the data for completeness, reasonableness, and accuracy.
